17 Claims. 1

Thepresent invention relates to a synchronizer formachines, suchas'glass machines. More particularly, it relates to a mechanism drivingtwo driven members fro-m a single power source and for automaticallydriving only one of them from another power source when-the first powersource is rendered inoperative. Stated more particularly, it relates toa mechanism by which a glass forming machine and a glass feeder may beoperated concurrently and in proper timed relationship from a powershaft, which mechanism automatically causes the feeder to continue tooperate from another power shaft without operation of the formingmachine, whenever the lat ter-is stopped. It preferbaly incorporates twoseparate motors, one of which usually is a large motor, and which drivesa shaft that is connected to the glass forming machine and drivesanother shaft which is connected through the synchronizing mechanism toa feeder operating shaft; andthe other of which is a smaller motorcapable of driving the feeder shaft alone, which smaller motor drivesthrough the synchronizing mechanism to the feeder shaft. The two drivesare connected to the synchronzing shaft through one-way clutches, andthe smaller motor drives the synchronizing shaft at a somewhat lowerspeed than that produced by the larger motor. Hence, when the largemotoris operating, it will operate the feeder shaft at a slightly greaterspeed than that applied by' the smaller motor; and the one-way clutch.permits the synchronizer shaft to run away from, or out from under, thesmaller motor shaft; When the larger motor is stopped, the smaller motoris effective to drive the synchronizer shaft, and in so doing causes thesynchronizer shaft to run away from the larger motor: shaft through theone-way'clutch between them.

It is an object of the invention to provide a composite synchronizingmechanism that may be connected to two separate motors, wherein onemotor may normally override the other motor and produce a driving forcefor a shaft on the output end of the synchronizer, but with onewayclutch mechanism between the larger motor and the synchronizing shaftand similar mechanism between the smaller motor and the synchronizingshaft, so that, when the largermotor operates, the small motor may idle,and, when the larger motor is inoperative, the smaller motor may drivethe synchronizer shaft without applying any load to the connections tothe larger motor.

' It is'afurther'objectof' the-inventionto on vide adjusting means forproperly synchronizing the output shaft of the synchronizer with thedriving mechanisms, and particularly for making the adjustment while themachines are oper= ating. It is a further object of the invention toprovide means for adjusting the speeds of the two motors in thiscombination individually, to obtain variable speeds for the glassmachines, and to obtain proper coordination of the large and smallmotors.

Particular objects include the details" of the means for adjusting thesynchronizer and details of the interconnections of the parts by whichthe foregoing main objects are accomplished.- An especial object is theprovision of a mechanism of this kind that is not only flexible in itsoperation, but also is rugged in all of its details.

This case is related to the application of Harold A. Yonkers, Serial No.711,948, filed November 23, 1946. The present application is directed toparticular structure embodying the broader in vention of the Youkersapplication.

Referring to Figs. 1 and 26, there is shown a glass forming machinegenerally indicated at 30. It may be, for example, one like thatdisclosed in the application of Samuel E. Winder, Serial No. 688,470,filed August 5, 1946, for Bottle Forming Machine. It has a table 3| thatrotates about a center shaft and is driven by gearing 32 operated from ashaft 35. A plurality of glassware molds are spaced equally around theperiphery of the table 3| and are successively introduced beneath aplace where charges of glass are emitted by a glass feeder and severedby shears. A horizontal plate 36, bolted to the base 31 of the formingmachine and to the floor, affords a supporting base for thesynchronizing mechanism.

The feeder is usually operated by compressed air or other power means,and may conventionally comprise a plunger reciprocating over an orifice,and shears for cutting off the gob or charge of glass that is ejectedfrom the orifice. The operation of the plunger and the operation of theshears are synchronized as through a feeder timer, generally designatedat 38. There is a shaft 40 that operates the feeder timer. Thisconstruction is conventional and will be understood. The relativearrangement is shown schematically in Fig. 26.

The drive to the two shafts 35 and is obtained by the present mechanism.To this end, there is a large motor 42 that is capable of driving theforming machine through the shaft 35 and the feeder mechanism throughthe shaft 40. This large motor is connected by a belt 43 into a P. IV.or a speed varying device 44. The P. I. V. 44 is connected by a belt 45to the shaft 35, which may be provided with bearings 46.

The shaft 35 is connected by a belt 41 to a shaft 48 which connects intothe synchronizer that is generally indicated at 50.

There is another smaller motor 52 that is capable of driving the feedertimer, but need not be large enough to drive the shaft 35. In view ofthe reduced power required for the secondary operation performed by thissmall motor, it is driven to apply power into the synchronizer 50.

The small motor 52 is not connected with the shaft 35, but does driveinto the synchronizer 50. While the shafts 48 and 58 are driven shaftswith respect to the motors, they are driving or power shafts withrespect to the synchronizer 50.

Referring particularly to Fig. 2, the synchronizer includes a lowerhousing 60, mounted upon the base 36, an intermediate housing 6| that isbolted at 62 to the top of the lower housing. Above the upper housing,there is a top housing 63 that is bolted at 64 to the top of theintermediate housing 6|. The top housing 63 is enclosed by a cap 65 thatis bolted to the top thereof.

Reference to the drawings will show that these several housings interfitby being provided with rabbets that engage in grooves, so that the partsare automatically positioned and held against movement. They thus may beassembled one on top of the other and finally fastened securely intoposition by the various screws. This simplifies the assembly. The bottomhousing 60 has a rear opening 66 enclosed by a cover 61 attached byscrews 68. This closure 61 may be removed to give access to the ratchetmechanisms, as will appear. The assembled synchronizer housing issecured to the base 36 by a series of bolts, as shown; or otherwise.

The bottom housing 60 has a bottom plate 69 therein, as shown in Figs.17 and 18, in which bottom plate a bearing 10 is mounted. This bearingsupports the lower end of a synchronizer input shaft II that extendsmedially upwardly through the lower casing 60. This shaft has a splinedupper section 12 that is ultimately supported in a bearing 13 located inthe center of a lower partition 14 in the bottom of the in termediatehousing 6|. The two motor or power shafts-48 and 58 are connected todrive the shaft 1 l, and the shaft H is a driven shaft with respect tothe power shafts 48 and 58, as well as an input shaft with respect tothe mechanism above it.

As shown in Fig. 21, the bottom housing 60 has a flat portion across itsupper part at the front of Fig. 2. This flat part 151s adapted toreceive a cap 16 that closes it and forms with it a worm gear casing anda journal casing for the shaft 48. The cap 16 is bolted at Ti to thefront panel 15. As shown in Fig. 10, the surface 15 extends along adiameter of the shaft 48, so that the cap 15 and the adjacent parts ofthe bottom housing 60 are cut away in complementary halfcylinders toform bearings 18 and 19, which may be properly bushed, as indicated, tosupport the shaft 48.

Within the casing thus provided, the shaft 48 has on it a worm 8| whichis rotated upon rotation of the shaft 48. This worm is intermeshed witha worm gear 82 that is rotatably supported on the shaft ll by beingmounted on a flanged spacer bushing 83 that surrounds the shaft I I.

The worm gear 82, as shown particularly in Figs. 17 and .19, has on its.bottom surface: an integrally formed, finished, plate receiving sec--1'I- in a similar manner. a bottom housing 60 is provided with; a flat.sec

show. that; it is turned upside: down flanges 86'; undercut as shown at.8 1 in. Fig. 20..

These two flanges 86 are adapted to: receive. a: ratchet dog plate 88,shown in detail in: Figs. 8

and 9 and appearing assembled. on thebotttom.

surface of one side of the worm gear M inFigs. l l andli. The plate 88is attached to the bottom::. surface of the worm gear 02 by three screws85 that extend downwardly from the top of the worm gear, as shown inFigs. 10 and 17.

, The plate 80 has a ratchet. dog pinlH pressed thereintoconcentrically,- with one of the; screw holes 85 in the worm gear. ThispirrQ-t is. tapped at 9-2 to receive one-of the screws89. A ratchet dog93 is mounted over. the pin t andmayrock thereon. This ratchet dog has agroove- 94' along. oneyside edge, in which one end of atorsion: springfits.v This spring 95. urges the dog 94: toward the shaft 1 I, and alsotends to prevent the ratchet. dog 93 from moving off the pin 9I.Thegspring 9.5 is wrapped around a spring holder button 96'. that issupported on the plate 88-. by ascrew that. engages in a hole 98 in the"plate 88.. The other end of the spring 95 is wrapped aroundl a screw 9.9that: fits in another threaded hole I00 of the plate 00., Movement ofthe ratchet. dog away from the shaft H islimited by a pin it pressedinto the plate 88. i

i The ratchet dog 93 is urged bythe spring 95 intoengagemen-t with aratchet disc I105. This ratchet disc has a peripheral flange I06 that isdescribed about the center of the disc, Above-the counterclockwisedirection, as viewedaimFigs. l0;

and 11, the ratchet. dog; 93 will causje-thedise- I05 to rotate: in acounterclockwise: direction, and; such rotation. will be imparted tothe-shaft 1 If.

that is identical with the plate 88 and is iden" tically mounted, thoughon an upper side. This: lower plate I28. has a pin I23 inits'uppersurface, upon. which a ratchetdog I30 may rock.

I This ratchet dog is identical with the ratchet dog 93, and has agroove I3I therein inwhich one end of a torsionspring I32 fits; Thistorsion ismounted' on a spring button I33 held to the plate I28 by ascrew. The other end of? the torsion spring I32 is engaged around ascrew I35. A limiting pin I36 is provided forthe dog. I30.

Reference to Fig. 17 will showthat the flange I06 of the ratchet discI05 extends betwee the: pins 9| and I29, upon which the two ratchetdogs:

I 93 and I30 are mounted. Hence these dogs cannot come off.

reference; to. the drawings; sucha tozsthe other wormxgean lt supp'oshoulder I01.

It will be seen that, when the worm gear [20- is rotated to move theworm gear I 2| counterclockwise, the ratchet dog I30 will engage withthe shoulder I40 and will move the shaft H in the same direction.

' The upper splined end 12 of the shaft 11 engages with acomplementarily splined miter gear" I50, which gear isrotatable in thebearing 13 and is supported in the manner shown. Around thehub of themiter gear I50, there is a cage I 5I that extends upwardly in theintermediate hens ing 6|. This cage is shown in Figs. 3 and 4' toinclude a bottom annular portion I52, two side portions I53 and I54, andatop flanged portion I55. This upper portion includes an extensionI56above the flange I55.

The lower annular portion I52 is provided withv a central opening,bushed at I51, through which the hub of the miter gear I50 passes. Thetwo" side arms I53 and I54 are providedwith bearing portions I58 and I50that receive a shaft I; This shaft has a head at its right end in Fig.2, by means of which screws I 6I mayattach the shaft to the cage I5 I.

The shaft has asuitable bushing between thesi'dearms I53 and I54, whichbushing. receives a. pair" of facing miter gears I63 and I64 which arerotatably mounted on the shaft. The miter gear shaft is provided with anoil groove I66;

The two miter gears I63 and I64 mesh with a top or drivenmiter gear I61.This gear is caused to pass through atop opening I60 in the cageI'5I'and to interfit with a bearing IBB'mounted ina depending circularflange I10 extending;

downwardly from the top housing, element 63. This mitergear I61 issplined to an end Il'I- of a shaft I12 that extends upwardly"through.the

partition across the bottom" of the top-housing 63 and into thathousing; A bushing I 13"sup'-' ports the top of the cage. I5I about" thehubof' the top miter gear I61.

From the foregoing; it may be-seen-that rota.-

tion of the splined end 12 of the shaft 11 will-1 cause rotationofthemiter gear I50. This; in turn, will rotate the two miter gears ['63and I64 about the shaft I60, and. they will: rotate the top miter gearI61 and the splined. end I1 0 of theshaft I12.

An adjustment is provided to adjust the relative angular positions ofthe shafts: TI and I12;

This adjustment is effected by rotatingthead justment cage I5I thatcarries thetwo gears I63and I64 about the centers of'the two. shaftsT-uand I 11'.

' :ic: thistend; designer rie erie on the flange I55, carries a wormgear I that is bolted to the two side arms by screws I16, and whichbears against the depending end of the flange I18 on the upper housingsection 63.

The upper part of the intermediate housing section 6| is providedwith afiat portion I18 (Fig. 22) over which a cap I19 fits, the cap beingsecured by screws I88. This cap, together with the adjacent part of theintermediate housing 6 I, forms a worm wheel housing and is providedwith complementary semi-cylindrical cut-outs to provide journals I8I andI82 for an adjustment shaft I83. This shaft I83 carries an adjustingworm I84 that intermeshes with a worm gear I15.

The shaft I83 extends outwardly from the cap I19 and has on its outerend a crank I 86, to which a crank handle I81 is attached. This crankI86 has a central hub I88 having a plurality of holes I89 drilled downinto the periphery thereof.

A locking pin bracket I98 is provided with a sleeve portion I9I and ahorizontal extension I92, which latter fits onto a finished flat boss onthe top of the bottom plate of the top housing 63, to which it isattached by a screw I93 and held against rotation by a pin I94. Thescrew passes through an opening I95 of the extension I92, and. the pinpasses through an opening I96 in this extension, entering similarlyspaced threaded openings in the said boss.

A locking pin I91 passes through the sleeve section I9I. It has a lowerportion I98 that is adapted to interfit into any of the holes I89,thereby to hold the crank I86 against rotation. There is an enlargementI99 just above the portion I98, which provides for a lower bearing inthe sleeve I9I. The upper end of the pin I91 passes'through anotherbearing portion, as shown in Fig. 14, and has a handle knob 288 at itsupper end. By means of this handle, the pin I91 may be raised out of anyhole I89 into which it is engaged.

From the foregoing, it may be seen that, if the knob 2881s lifted, thecrank handle I81 may be operated to turn the shaft I83. This rotates theworm wheel I84 and moves the worm gear I15 about the shaft centers. Asthis worm gear I15 is attached to the cage I5l, the latter will berotated. The cage is rotatable with respect to both of the miter gearsI58 and I61, but rotation of the cage causes the shaft I68 to be rotatedor turned end over end, varying the two miter gears I63 and I64 toultimately adjust the shaft I12 with respect to the shaft H. The knob288 is provided with a cross pin 28I to engage in slots 282 in themember I98.

As noted, the shaft I12 projects up int the top housing member 63. Theshape of this housing member is indicated in Figs. 2, 23 and 25. Fig. 23is a top view of the top housing 63 and shows that this housing is madeup of a bottom plate 295 that is circular and may fit over the top ofthe intermediate housing 6|, to which it may be held by the screws 64.The shaft I12 is adapted to project through an opening 286 concentricwith this partition or bottom plate 285. There is a groove 281 aroundthe opening 288 to receive a bearing 288 for the shaft I12.- Above thebearing 288, there is a spur gear 289 that is keyed to the shaft I12.This spur gear intermeshes with a gear 2I8 on a stud shaft 2I I. Thestud shaft is mounted in a bearing 2I2 that is supported in a bearingrecess 2I3. It is also borne by a bearing 2I4 in the cap member 65.

The stud shaft 2 receives a gear 2I5 of con siderably larger size. Thisgear 2I 5 meshes with 't0 the shaft I12.

Operation The motor 42 drives the shaft 48 at a speed slightly in excessof the speed given to the shaft 58 by the smaller motor 52. It ispreferable to provide such speed differential, to enable the main motor42 to carry the load of the shaft 48, and thereby insure absolutesynchronism of the shaft 48 and the shaft 35. If the motor 52 drives theshaft 58 at a speed to turn the shaft 12 at a speed greater than thespeed imparted thereto by the shaft 48, the exact synchronism may belost. If the two power shafts operate the shaft 12 at exactly the samespeed, synchronism is obtained, but, for obvious practical reasons, thiscondition is hard to obtain and maintain. Hence it is best to operatethe smaller motor at a speed to drive the shaft 12 somewhat slower thanthe speed produced by the main motor 42. Furthermore, when the motor 52alone is operating, the forming machine is inoperative and the feeder isoperating only to keep the glass from freezing in the forehearth andorifice. It is normally unnecessary to operate the feeder at its fullspeed to prevent freezing.

When the motor 42 is put in operation, it will drive through thevariable speed reducer 44 to operate the shaft 35 and thereby cause theglass forming machine to function. At the same time, the belt 41 willcause the shaft 48 to rotate. The shaft 48 will rotate the worm 8I andcause rotation of the worm gear 82, which is capable of turning on theshaft II However, the ratchet dog 93 is mounted on the Worm gear 82, sothat the dog 93 may be brought against the shoulder I81 on the ratchetdisc I85. This will cause the disc I to be rotated, it becoming a powertakeoff element to the ratchet dog 93 and the gear 82. The disc I85 isgeared to the shaft 1I. Hence, that shaft rotates. The shaft 1I, beingsplined to the lower miter gear I58, causes that gear to rotate.' Suchwill rotate the two miter gears I63 and I64 about their centers on theshaft I68, and this movement, in turn, will cause rotation of the topmiter gear I61, which is splined Consequently, the shaft I12 rotates.It, in turn, is keyed to the spur gear 289, which meshes with the gear2I8 on the stud shaft 2I I. The stud shaft is keyed to the big gear 2I5which is caused to rotate. This gear meshes with the gear '2 I 1 on theshaft 2I8. This shaft thereby rotates and causes the feeder shaft torotate.

Thus, when the large motor 42 operates, it causes the forming machineshaft 35 to operate -;to"drive the forming machine and, at the sametime, itcauses the shaft 48 to rotate at a prop-. erly related speed tocause the feeder timer to move. As a result, the forming machine may, intypical conventional mechanisms, introduce molds successively to thefeeding point below the feeder. At the same time, the feeder plunger orconfined air column is actuated to eject the charge of glass to theorifice above the mold,

: a (1,.When a proper charge has been thus ejected,

feeder shears arecaused to sever the same 9 sdrthat it may fall into thewaiting mold. The feeder timer38, typified in Fig. 26, is the mechanismused to cause the feeder and shears to operate. it frequently consistsof a cam shaft operating a plurality of air valves in a fixed timedre'1ationship.

It'is highly desirable that the feeder continue to operate, even whenthe molding or forming machine is stopped. In the present mechanism, ifthe motor 42 is stopped, the motor 52 will continue to run and rotatethe-shaft 58 at a speed below the speed that the shaft 48 had when itwas operating: "The shaft 58 drives the worm 12.0, which meshes with theworm gear l2-! and causes it to rotate about the shaft "H. However, theratchet dog E30 is urged by its spring 1 32 into engagement with thelower part of the :ratchet .disc 1.05. It may therefore be brought intoengagement with the lower shoulder Mi! on the ratchet disc to cause thisdisc to operate. This rotation is transmitted :to the output shaft A inthe same manner as previously described in .oonriection with the drivefrom the larger mo- :itor 42.

:When the larger motor is operating through the synchronize! androtating the shaft 4-8, the upperworm gear :82 will :be driven. If thelower :WQlTm gear 1-21 is simultaneously being driven from the shaft 158and the smaller motor 52 ata lower peed than the upper worm gear .82 .is

repair of the ratchet parts.

The various housing portions may be easily separated. For example, ifthe screws 225 are removed, the cap 65 can be withdrawn and the partslocated within the top housing 63 may be worked upon conveniently. Ifthe screws 64 are removed, the mechanism enclosed within the top sectionmay be lifted off of the upwardly projecting shaft I12. If it is desiredto repair the worm .gear drives, the screws 62 may be removed and thewhole assembly from the intermediate housing 6| on up may be lifted offbecause of the spline between the shaft 12 and the gear I50. It isfairly evident that the parts in the lower housing may be easilyremoved.
